I think you make some valid points there Nucleo. I also think damage to the "outer" haircells has some contribution to the development of H &T aswell, but this damage would neither be shown in an audiogram. As their function is as I believe to attenuate loud sounds and louden the perception of low sounds. I took a test that confirmed outer haircell damage. And the T-expert seemed to be more concerned about that than my audiogram.
You took a distortion product oto-acoustic emission test I presume?
